states that one quantum is absorbed by the molecule responsible for the primary photochemical process. After absorption, the excited molecule can then undergo various reactions. It can form a product, it can catalyze a chain reaction, or it can get de-excited. If on absorption of one photon, one ..

Nitrogen readily combines with highly electropositive metals (Group 1), even at room temperature, to give nitrides. For example,..

Halogens have very high electron affinity values and therefore, have very strong tendency to gain an electron. Thus halogens are very reactive elements due to their low dissociation energies and high electron affinity values. As clear from the values of bond dissociation energi..

Electron affinity is the amount of energy released, when an isolated gaseous atom accepts an electron to form a negative ion. The other atom participating in the formation of an ionic compound must form an anion by gaining an electron (s). Higher electron affinity favours the formation of an anion..

Elements that have higher ionisation energies cannot form ionic bonds, as they cannot lose electrons easily. Instead, they acquire stability by mutual sharing of electrons, and therefore form covalent bond..

Example 11: The rate constants of reaction at 700 K and 760 K are 0.011M - 1 s - 1 and 0.105 M - 1 s - 1 respectively. What are the values of 'A' and 'E..

High nuclear charge and smaller atomic size leads to the increase in Ionisation energy of the combining elements.Therefore it favours covalent bond formation, because the transfer of electrons in such cases will not be possibl..
